置。[Scope of Claim for Utility Model Registration] (1) Metal wear amount detection that detects a predetermined amount of wear of the bearing metal at a predetermined depth inside the bearing metal of a metal sliding bearing used for a rotating bearing of a water treatment machine submerged in water. A bearing device for a water treatment machine, characterized in that a bearing device is provided with a means. (2) As the metal wear detection means, one conductor with an insulating coating is placed deep inside the bearing metal.
Claim 1, wherein when a set or a plurality of sets are fitted and the wear of the metal reaches a predetermined amount, the insulating coating is scraped off and the wear is detected by an electric signal generated by establishing continuity. Bearing devices for water treatment machinery. (3) As the metal wear amount detection means, an optical fiber cable is fitted into a predetermined depth inside the bearing metal, and when the metal wear reaches a predetermined amount, the wear is detected by an electric signal generated when the optical fiber cable is broken. 2. The bearing device for a water treatment machine according to claim 1, wherein the bearing device is configured to detect:
